Specification of Letters Patent No. 17,476, dated January 22, 1840.

T 0 all @071cm t may concern Be it .known that l, Doumer D. Snoirnr, of

'l/Vcsttield, Hampden county, State of Massachusetts, have invented a new and useful Improvement in Braiding-ldachines, which is described as follows, reference being had to the annexed drawings of the same, making` part of this specification.

In the original braiding machine, patented by John Thorp nearly twenty years ago, there. existed serious defects, such as the liability of the racers becoming deranged by dodging the cant wire and also in the complexity of the racer itself, together with the immense friction in the running of the racer and likewise the difficulty of securing the spool wire to the racer. rJShere existed likewise defects in the subsequent improvement on said Thorps machine invented and patented by Seymour Halliday, such as propeiling the racer byl a stud projecting from the back of the racer which caused it to render; likewise in its liability to dodge the point of the form and circle; and the existence of the evil arising from' the rubbing or friction of the racer in passing over the stationary oval forms.

My improved machine for which I now solicit Letters Patent is designed to obviate the before mentioned defects.

The nature of the invention and improvement consists in running the racers in such a manner and by such means as to prevent them from taking the wrong course and thereby becoming deranged or misplaced; which iseffected by suspending a winged ily guide at the top and bottom of each changing place ofthe racers attached to the inside of the upper and lower circles by a bolt passing through the head of the winged fly guide into the circle so as to allow it to vibrate on said bolt at every passage of the 'racer between the guide and form and thus prevent the derangement or wrong running of the racer. Also in having a number of round smooth wheels or forms attached to the revolving gearing; which gearing being from one-fourth to half an inch thick and having a projection starting at the base or roots of the gearing extending inward half the thickness of the gearing and in that projection forming four cavities or scallops of equal size from which the racers receive their motion-the racer 4being formed with a round plate the section of a sphere attached to the shoe of the racer, which plate enters said cavities. 1

To enable persons skilled in the art to make and use this improvement I will proceed to describe its construction and operation.`

Figure l is a vertical section of the inside of the machine showing part of the upper and lower circles -several of the revolving forms or wheelsracers and spools--y and winged fly guides. Fig. 2 is a vertical section of the outside of the machine showing part of the circular rimupper and lower circles knees racers gearing studs, &c. F ig. 8 is a perspective view of one of the racers detached from the machine. Fig. 4lis a sectional view of one of the revolving forms o-r wheels, showing the cavities therein. F ig. 5 represents one of the winged fly guides.

The Vcircular rim, knees', upper and lower circles, gearing, arbors and spools being made, arranged and operated like those in the machines referred to, whichare well known, need not therefore be described.

My improved racer A consists of a circular back plate A made concave on the face toward the shoeand convex on the outside, cast with the shoe B, which plate is brought to nearly a sharp edge in front to prevent its catching on the circle, said racer being propelled by a carrier or revolving form C of a peculiar construction attached tothe gear and revolving with it. This carrier wheel or revolving form C is made by placing. a scalloped plate VD against the concave face of the cog wheel and then placing a circular flanged wheel or form C against said scalloped plate and securing them together by riveting or otherwise, forming spaces or cavities to receive the racer plate A.

The wires E for holding the spools are passed through the shoe and plate and are secured on the outside of the plate.

The winged fly guide G for changing the direction of the racers is composed of a metallic casting or wrought iron piece forming a head and tail and having two curved wings; that which isattached to the upper circle ishung to a bolt or pin H passing through said circle with the tail end suspended between the revolving forms C. Those attached to the lower circle are placed in a reverse position-that is to say tail upward and in every alternate space around the. circle. All the iiy guides around the circles are made alike. The racers, carriers,

and forms arranged around Athe circles are also formedlike that above described.

The spools containing the thread to be braided are arranged Von the racers in the manner of the machines referred to vand theV article to be braided is held in the centerof the circle in the VAmanner ofthose machines.`

Mode of operation: The racer-AV being in theposition shown in the drawing in Fig.

1 liftsthe right wing of the fiy guide GY, at the same time bringing the tail endagainst the periphery of form C and making aV vpassage Vfor racer A. totravel to the left around form Ce-.which movement forms the. npper stitch. To form the lower stitchthel .lower ily guidejGl, in a reverse position,is

required to operateivhich is performed as' follows: When the racer Am Vstrikes the wing of guide G in passing around form 0 in the direction of the arrow itY moves the mii of this fly/'guide o against form VCI and makes room for racer A" `to pass ori to Sform G` traveling in an opposite direction to racer AVV-and in this manner the purpose and in the manner described.
